Patent JP-H0481276-A (JP)
Title: Ac arc welding machine
Inventor: HARADA SHOJI
IPC: B23K9/09
Filed: 1990-07-19
Abstract: PURPOSE:To carry out control by a program in the middle of welding by providing a signal converter circuit in which the length of each period of the straight polarity and reversed polarity is made into a voltage signal which is converted into a pulse signal having time width in proportion to this voltage signal. CONSTITUTION:The output voltage (a) of a time setting circuit 1 is converted into a reciprocal k/a by a divider circuit 2 and supplied to a V/F converter circuit 3 and the input voltage is converted into the pulse signal (p) of frequency in proportion to an input voltage value. This pulse signal (p) is counted by a preset counter 4 and when this pulse number attains a set value, the preset counter 4 reverses an output signal from a low level to a high level. When the output signal of the preset counter 4 is reversed to the high level, a monostable multivibrator 5 is triggered by this rising and the output signal is made to the high level for a specified time determined by a resistor R. when the output of the monostable multivibrator 5 is taken out to an output terminal T1 as one time signal and a signal produced by reversing this signal by an inverter is taken out to an output terminal T2 as the other time signal, time signals to reverse alternately can be obtained.

Title: Eddy current detection of flaw on roll surface
Inventor: KAWAMURA KOUJI
IPC: G01N27/90
Filed: 1983-10-14
Abstract: PURPOSE:To enable prompt judgement of the presence or absence of any flaw, the kind of whether a cracked flaw or decreased hardness, the size of the flaw and the shape of the flaw by comparing the two-dimensional flaw map which is analogically and digitally displayed. CONSTITUTION:The eddy current flaw detection signal from a detector 4 is divided to two. Phase shifters 7 and 13 rotate said signals to the phase angles at which a crack flaw and hardness decrease are detected respectively with good S/N. The signals are then inputted to phase detectors 8, 11 and are synchronously detected. The signal A past a filter 9 set at the high frequency band where the crack flaw is easily detectable is lowered in the frequency level of the flaw signal by a peak expander 14 and is analogically recorded like (c) in an X-Y recorder 19 in synchronization with a probe position detector 23. The output B of a filter 12 set at the low frequency band where the hardness decrease is easily detacable enters a divider circuit 16 together with the output A, by which B/A is calculated. The crack flaw and the hardness decrease are discriminated from the value thereof and the result is digitally displayed like (b) on a CRT or printer.

Title: Manufacture of solute for nonaqueous electrolyte
Inventor: YOSHIMITSU KAZUMI
IPC: C01B25/10
Filed: 1982-11-01
Abstract: PURPOSE:To improve the characteristic of a battery by removing acid impurity by adding a specified treatment agent in recrystallizing crude LiPF6 in an organic solvent so as to neutralize the solution in manufacturing a solute for a nonaqueous electrolyte consisting of LiPF6. CONSTITUTION:Crude LiPF6 containing acid impurity is first dissolved in an organic solvent. As the organic solvent, a matter of a high permittivity having a polar group such as an ether bond or an ester bond is preferably used. At this point, the temperature of the solution reaches 60-70 deg.C due to the heat of the dissolution. After that, the solution is neutralized with a Li compound or an amine while maintaining the temperature by external heating. The neutralizing agent may be anything which can combine with acid impurity especially hydrogen fluoride to form a salt or a complex compound. The ratio of the neutralizing agent to crude LiPF6 is 1-20pts.wt. to 100pts.wt. After the neutralization treatment, the solution is filtered while being maintained at the above temperature to remove excessive amounts of the treatment agent and reaction products dispersed and suspended in it. Following that, when the filtrate is cooled to around room temperature, LiPF6 contained in the filtrate crystallizes and deposits which is then filtered off thereby obtaining desired purified LiPF6.
